Infrared cirrus

As infrared cirrus weak infrared radiation is described by interstellar dust in the Milky Way.

The temperature of the dust grains is in the range of 30 to 40 K. The infrared cirrus is at least 1000 AU from the sun and this is different from the much warmer and closer sun zodiacal light.

Infrared Cirrus is a high probability of dust particles that are not greater than that of tobacco smoke. The particles are thought to consist in supernova explosions or stellar winds entstandenem auskondensiertem carbon.

The name has its origins in cirrus clouds resembling appearance of the infrared cirrus computer images on.
